Distance Map Generator

Distance Map Generator is a tool for creating distance maps inside Unity. It generates very good maps from small anti-aliased source textures. No need to generate huge source textures to get a nice distance map.

generate distance maps from small anti-aliased textures

Distance maps can be generated via an editor window or via scripting. You can find more information in the documentation, the Unity forum topic, and a short demonstration video

The tool is available for free under the GNU GPL and can be downloaded here.

The algorithm used by the generator is the anti-aliased Euclidean distance transform described by Stefan Gustavson and Robin Strand. See http://webstaff.itn.liu.se/~stegu/edtaa/ and http://contourtextures.wikidot.com/ for further information.
